TORONTO - Running back Chad Kackert has suffered a setback in his comeback bid with the Toronto Argonauts.

Kackert was injured during a non-contact scrimmage Tuesday when he made a sharp cut on his left leg while carrying the football.

He walked to the locker-room following practice on his own, but with a limp. He didn't speak to reporters.

The five-foot-eight 206-pound Kackert came out of retirement late last month to join the Argos practice roster.

Kackert retired on the first day of training camp to become Toronto's strength and conditioning coach after suffering a broken left ankle prior to the 2013 East Division final. It was unclear if Kackert re-injured the ankle.

Kackert, 28, was a big-play running back during his three seasons with Toronto, rushing for 1,467 yards and 12 TDs on 228 carries (6.4-yard yard average). He added 50 catches for 454 yards and two touchdowns.
